In the drawings, in which I have shown my improved-roller bearing as" applied for use in connection with ajivheel hub and axle, 1 designates the axle and 2a hub bearing cular seriesitype, andit primarily haslfor its object to provide a bearing nearly frie tionless as poss i'ole, while, at the same time,

providing a bearing of the typementioned of a simple, effective andinexpensivecon struction and which will readily serve itsintended purposesf i My present invention also hasfor itspurpose to provide an improvedrollerbearing 'of the general character statedinW-hicl the parts 'are designedt'or 'bein'g interchange able T and J replaceable" when conditions "may require it. Y

My present-invention, in' its generic na ture, embodies an improved arrangement of a bearing sleeve removably mounted-0n an .axle'or shaft, a series of main bearing rollers members 6-6, each of wh ch has an, internal arranged around and having bearing on the opposite ends only on the said sleeves, hub portions-for engaging the saidopposite ends of the main bearing rollers, a series of intermediate bearing rollers arranged around each alternate ones of'the main bearing rollers, a sleeve or casing that takes around. the series of intermediate rollers and which has contactwith tlie'ot'her alter-' p "of the drawings-{it will be noticed that my complete'roller' bearing includes a series-of mainrollers 55ya-lternately disp'osed relanate ones of the main rollers without thein termediate rollers, and a hub or spokes spreader tha-tztakes over'all of the roller bearing membersand is held outof contact therewith; l 1

Among otherspecial points of v advantage is that the only'bearing points are those ar- 5 rangedfin circular series-and which engage the hub bearing and which are engaged by thewheel hub sections continuously rotative in like directions and the main roller bearof the said rollersibeing arranged in circular series and a'continuous spreader-casing that takes around'all'of the circular series of rollers. 3.
